Allow quick and simple conformance checks on Lovibond instruments. Each filter set consists of colored glasses representing a spread of colors from the scale of interest, which are mounted in suitable holders. They are supplied in a presentation box with a Certificate of Conformity that states the actual values for each filter and confirms that they have been manufactured and inspected under the control of an ISO 9001: 2000 Quality Management System. In addition,Tintometer's ISO 17025 accredited calibration laboratory can supply glass filters for Lovibond instruments with color measurements that are directly traceable to national standards.

Note: Conformance filters are assigned a nominal value and Lovibond Tintometer always endeavors to match this value as closely as possible. On occasion, because of the unique manner of the glass making process, it may not be possible to match the requested values exactly. The values achieved and the performance tolerances expected will, of course, always be reported.
